1.2 Isocyanate (ISO) Conditions
Important Information Regarding Two-Component
Material. Read before using the equipment.
Isocyanate (ISO) Conditions
• UseonlyMethyldiisocyanates(MDI).
• Sprayingmaterialsthatcontainisocyanates(ISO)creates
mists,vaporsandatomizedparticulatesthatarepotentially
harmful.
• Befamiliarwiththespraymaterial’sMSDSinorderto
understandspecichazardsandnecessaryprecautions
that are related to the use of spray materials containing
isocyanates.
• Provideextensiveexhaustandfreshairintroductiontokeep
the air within the spray area free from harmful isocyanate
vapors.Ifsucientventilationisnotavailable,asupplied-air
respirator must be available to everyone in the work area.

To prevent contact with isocyanates, all persons located
within the spray area must be wearing the appropriate
protective equipment, including chemically impermeable
gloves, boots, aprons and goggles.

• Cross-contaminationofindividualspraymaterialscanresultin
cured material in uid lines which can cause severe injury and/
or damage to the equipment.
• Topreventcross-contaminationoftheequipmentwetted
parts, NEVER interchange Component A (isocyanate) parts
with Component B (resin) parts.
Moisture Sensitivity
Isocyanates (ISO) are catalysts used in two-component foam and
polyurea coatings. ISO will react with moisture (such as humidity)
to form small, hard abrasive crystals. These crystals will then
contaminate the uid. Eventually a lm will form on the uid
surface and the ISO will begin to gel, increasing in viscosity. Fluid
contaminated with partially cured ISO , if used, will reduce spray
performance and the overall life of the component wetted parts.
i
The amount of lm formation and the rate of
crystalization varies depending upon the blend of
ISO, the humidity and the temperature.
PREVENTION:
• Alwaysuseasealedcontainerwithadisiccantdryinginthe
vent,oranitrogenatmosphere.NEVERstoreISOinanopen
container.
• UseONLYthemoisture-proofhosesspecicallydesignedfor
ISO that are supplied with your system. If new hoses need to
be ordered, contact Titan Technical Service.
• Neverushreclaimedsolventsthroughthesystem.
Reclaimed solvents can contain moisture. Always keep
solvent containers closed when not being used to prevent
moisture contamination.
• Neverusesolventononesideifithasbeencontaminated
from the other side.
• AlwayslubricatethreadedpartswithISOpumpoilorgrease
when reassembling.
Changing Materials
• Whenchangingspraymaterials,thoroughlyushthe
equipment multiple times to ensure that it is fully clean.
• Alwayscleantheuidinletstrainersafterushing.
• Checkwithyourmaterialmanufacturerforchemical
compatibility.
• MostmaterialsuseISOwithComponentA,butsomeuseISO
with Component B.
• Epoxiesoftenhaveamines(hardener)withComponentB.
Polyureas often have amines with Component B (resin).
Foam Resins with 245fa Blowing Agent
Some blowing agents will froth at temperatures above 90º F (33ºC)
when not under pressure, especially if agitated. To reduce frothing,
minimizepreheatinginacirculationsystem.
1.3 Electric Safety
Electric models must be earthed. In the event of an electrical short
circuit, earthing reduces the risk of electric shock by providing
an escape wire for the electric current. Connection to the mains
only through a special feed point, e.g. through an error protection
insallationwithINF<30mA.
DANGER — Work or repairs at the electrical
equipment may only be carried out by a skilled
electrician. No liability is assumed for incorrect
installation. Switch the unit o. Before all repair
work, unplug the power plug from the outlet.
Danger of short-circuits caused by water ingressing into the electrical
equipment.Neverspraydowntheunitwithhigh-pressureorhigh-
pressure steam cleaners.
Work or repairs at the electrical equipment:
Thesemayonlybecarriedoutbyaskilledelectrician.Noliabilityis
assumed for incorrect installation.
Operating Temperature
This equipment will operate correctly in its intended ambient, at a
minimumbetween+10°Cand+40°C.
Relative Humidity
The equipment will operate correctly within an environment at 50%
RH,+40°C.HigherRHmaybeallowedatlowertemperatures.
Measures shall be taken by the Purchaser to avoid the harmful eects
of occasional condensation.
Altitude
This equipment will operate correctly up to 2100 m above mean sea
level.
Transportation and Storage
This equipment will withstand, or has been protected against,
transportationandstoragetemperaturesof-25°Cto+55°Candfor
shortperiodsupto+70°C.
It has been packaged to prevent damage from the eects of normal
humidity, vibration and shock.
